spark无法执行pi_如何验证spark搭建完毕

在配置yarn环境下的spark时，执行尚硅谷的以下命令发现报错，找不到这个也找不到那个，尚硅谷的代码是

bin/spark-submit \ --class org.apache.spark.examples.SparkPi \ --master yarn \ --deploy-mode cluster \ ./examples/jars/spark-examples_2.12-3.0.0.jar \ 10

正确代码是：

bin/spark-submit --master yarn --deploy-mode client --class org.apache.spark.examples.SparkPi /opt/module/spark-yarn/examples/jars/spark-examples_*.jar 10
